St. John's Lutheran Church in Des Moines is adorned by peace signs and doves made with sand on the sidewalk. I'm not sure what their intent was, but I like the symbolism. The symbols themselves are obvious, and appropriate during Holy Week, I believe. But, the fact that they are made out of sand is what I find interesting. It's not something that is permanent. The rain, wind, and people walking by without noticing can destroy them. Who knows, they could be gone by now. Symbolically, we can have peace and find Jesus, but these are things that we have to be conscious of and constantly work toward.
